Built from micrograin carbide and finished with a TiCN coating, it delivers extended tool life in ferrous and non-ferrous materials. The 2-flute, 40-degree helix spiral flute geometry promotes efficient chip evacuation and smooth cutting action. At 6 inches overall length with a 3-inch length of cut, this is an extra-long configuration suited to deep-pocket and extended-reach operations. The centercutting design allows plunge entry directly into the workpiece. CNC machinists and tool-and-die professionals are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical and horizontal milling centers where extended reach into deep cavities or tall workpiece features is required. The 3\/4-inch diameter and matching 3\/4-inch shank diameter make it compatible with standard ER, side-lock, and shrink-fit toolholders of that bore size. Right-hand cut and right-hand flute direction conform to conventional spindle rotation on most CNC machining centers. Typical applications include die milling, mold work, and deep-slot cutting in steel, stainless, cast iron, and hardened materials where a TiCN-coated micrograin carbide tool is the appropriate choice.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiCN finish for improved hardness and reduced tool wear in ferrous materials\u003c\/li\u003e\n\u003cli\u003e40-degree spiral helix promotes efficient chip evacuation and reduces chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003eExtra-long configuration with 3-inch length of cut and 6-inch OAL for deep-reach operations\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for CNC milling applications requiring a 3\/4-inch square end mill with a 3\/4-inch shank in extended-length configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified CNC machinists or toolroom personnel. Ensure the spindle is fully stopped and the machine is in an E-stop or powered-down state before changing tooling. Seat the shank fully and evenly in the toolholder and torque retention hardware per the toolholder manufacturer specification. Verify runout at the tool tip with a dial indicator before beginning a cut to avoid premature tool wear or workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12181771\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727179055410,"sku":"12181771","price":312.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cec6b0ba54fce7a196a85a21433e89f7.jpg?v=1788674376","url":"https:\/\/voomisupply.com\/products\/accupro-12181771-square-end-mill-3-4-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
